Our API design and automation instructors are API architects and developer experience specialists who have designed OpenAPI specifications for public and internal APIs at software companies, helped teams adopt Swagger tooling, and built advanced Postman automation frameworks for CI/CD pipelines. They teach API-first design as a discipline, not just a documentation practice.
